First world problems: Lack of chickens
When traveling I always found that seeing chickens everywhere (and I do mean everywhere) was a good proxy that a country was not quite 'westernized'. The developing world has long ago figured out the value of chickens as an inexpensive source of protein.
Bill Gates must have some pretty good handlers for him not to notice during all of his trips. Real, non-factory chickens are fast and nearly impossible to catch or chase away. All I can imagine his plan doing is ruining the genetic stock of the local breeds into sickly flavorless creatures that can barely keep themselves alive creating a greater burden on the community. If people can't raise chickens in these areas it's a sign of something much worse going on that should be addressed instead.
